This bracket is provided with a pair of spaced ears or arms 34 which project outwardly to the outside of the windshield frame through a longitudinal slot 35 formed therein. This bracket 33 is provided with a pin 36 adapted to work longitudinally'in the slot 22 of the latch bar and when the latch bar is rotated to enter one of the registering lateral slots 23.

Pivotally connected to the spaced arms 34 of the bracket 33 as at 37, is a link or arm 38 which has its other end pivotally connected as at 39 to the corresponding side pillar 12. The laterally extending slots 23 are so located with respect to the length of the member 21 that the pin 36 of the bracket 33 will register with one of these slots 23 in the closed position of the windshield and also with other of these slots 23 when the Windshield has been adjusted to diiferent open positions. Whenever the pin 36 is brought opposite to one of the lateral slots 23, the spring 30 will rotate the member 21 to cause the pin to enter the slot 23, thus holding the windshield from further movement until the latch bar 21 has been rotated to free the pin 36 from the slot 23.

For rotating each member 21 against the action of its spring 30 for the previously described purpose, I provide an operating handle 40 arranged substantially centrally of'the windshield. Rotatably journaled in the lower windshield frame member 16 is a cam member indicated generally by the reference character 41, see particularly Figures 2 .and 6. This cam member has .a flattened or cam portion 42 and a reduced portion upon which a bushing 44 is placed, the handle 40 being secured to the end 45' of this cam membero On each side .of'the flattened or cammed portion 42 is a cam block 46 to which one of the rods31 is attached. The'cam portion 42 acts to move the cam blocks-46 apart so'that a movement of the handle' in the direction indicated by. arrow A pulls the rods 31 in the direction of arrows B, see particularly Figure 1. Fixed to. one of the rods-31 is a spring retainer in-the form of a cup-like member'47'within which one end of the spring48, is placed. The other end engages the adjacent cam block 46 and the tendency of the spring 48 is to move the cam blocks towards one anotherv and to hold them in engagement with the cam portion of the cam member.

The end of rod 31 to the right in Figures 1 and6, passes over the cam 41 and engagesthe cam block 46 to theleft. The cup-like member 4'7 is fixed to theleft hand rod 31'and this rod passes under cam 41 and isattached to the right hand cam block 46. .Thus a singlespring acts to hold both cam blocks in engagement with cam 41. f f

By reference to Figures 7' and 8 it will be noticed that the sill member 11 is recessed or cut awayas at 49. to accommodate the cam member 41 and the adjacent face of the cut away portion 49 is provided with an. inclined cam surface 50 terminating ina shallow recess 51. Carried by the cam member 41 is a radially extending cam pin 52 which is rotated when the handle '40- is rotated. When the windshield is closed the handle may be -rotated to cause thispin 52 to engage the inclined surface 50 at the point 53 andby the continued rotation of the handle the pin iscaused'to travel along the inclined surface 50 which acts to draw the windshield'tightly against the frame members around the windshield opening, the handle being rotated until the pin 52 enters the recess 50 whereupon the against the adjacent frame surface so that a water-tight seal throughout the'periphery of the windshield is provided.

The operation oi'the devicefiwill be apparent. 7

From closed position the-windshield is first unlocked by rotating the handle 46'to cause the pin 52-to clear the cam surface 50 and at the same time to actuate the rods 31 which rotate the latch bars 21 at both sides of the windshield which disengagesthe lateral slots 23' upon the pins 36. Thereupon these pins are in alignment with the longitudinal slots 22 in the members 21. The windshield may thereupon be'pushed or swung.

outwardly and if the*hand1e is not held to resist the turning movement of the springs 30, when the pins 31 come into registration with the next lateral slots 23, the springs 30 will'partially rotate the members 21 and the windshield will be number. of the lateral slots 23. To :close the windshield the operation is reversed andthe handle 40 is operated to rotate the latch bars 21 to position the pins 36 in the longitudinal slots whereupon the windshield may be moved to closed position and lockedbyengagemen't of the 1.
